It depends on if it treats it as:(-5)² or -(5²)
(-5)² is +25, -(5²) would be -25.
EDIT: Answer keys may have errors in it. I've seen it happen, and once it's found, good teachers will not it and let the kids know next time the book is used so they're made aware of it.

I'm with you. +25
Unless the question is -(5^2) in which case the negative would be applied after squaring it.
But typos do happen. Maybe there is a correction online.

when you take a number to a negative power, is is 1/(number to the positive power) 5 to the 2nd is 25 1/25= 5 to the -2 other examples 4 to the -3 = 1/(4 to the 3)= 1/64 2 to the negative 5= 1/(2 to the 5)= 1/32

is it like(-5)^2 or like this-5^2 if it is the first one then it is 25 if it is the second one it is -25

-5^2
= (-5)(-5)
= 25
= (-5)(-5)
= 25

it is +25. A square is ALWAYS positive.
it could be -(5^2) instead of (-5^2).... maybe perhaps?
